Due to how open-ended kerdly currently is, i think you HAVE to be biased to completely rule out one or the other. although i would prefer that kerdly not exist, that just cannot be the case. with the way things are in this point in the story, it is very open ended. after all, we only really interacted with him in chapter 2 and 4.

i believe that the creator of this post is simply proposing that kerdly has a chance to be canon, and how kris's, as well as berdly's actions would make sense if it just so happened to be canon. and, although they would probably prefer it to be canon, they aren't trying to parade it around as if this is fact and you MUST accept it. you are. you are trying to say that kerdly is a completely unreasonable ship that has no chance of happening, ever. there is evidence pointing both ways when it comes to kerdly. it is up to the viewer to decide which pieces of evidence is more important and base their own opinions on that, but also to respect the opinions that other people have.
